well the worst thing you couldve done is not let the car dry 100% before you tried to start it.
if you take out your battery and park your car in a pool take it out and let it sit there for 3-4 days in HOT HOT HOT weather and make sure there is no more water ANYWHERE and go to start it the water has no effect. Obviously this is a perfect situaution and not yours... but still throwing it out there. if something is wet. dont try to **** with it till its dry.
